SPECIFICATION' forming part 'of LettersvPatent No. 754,549, dated March 15, 1904, Application fue@ January 1s, 1904. serial No. 189,499. N0 modem To aZ whom it petty concern:

Be it known that I, CHRISTIAN F. DIEfrz, a citizen-of theUnited States, residing atChicago, in the county ofCook and State ofIlli- 5 nois, have invented a new and useful Improvement ,in Cream-Roll-Forming Machines, of which the following is a specification.

My invention relates to an improved machine for use in forming the crust portion in I what is known in the baking art as creamrolls. This roll is a wellknown bakery Y product, consisting of a spiral crust, usually of slightl'ytapering shape, and filled with creamor the like.- In theproduction of the I crust portion of the roll a narrow strip of dough is wound spirally upon a hollow tin form and baked thereon, the tin form being frusto-conical to facilitate removal therefrom of the baked crust, which is afterward filled,

2O as stated. It has been usual hitherto to wind the doughv upon the tin altogether by hand,

an operation necessarily slow and laborious,

and as many of the large bakeries turn out thousands of such cream-rolls each night necessarily skilled labor required for forming them altogether by hand has rendered the product comparatively expensive.

My object is to provide a machine of simple and improved construction by the use of which the production of cream-roll crusts as described may be greatly facilitated.

Referring to the drawings, Figure l is a partlysectional elevation of my improved machine; Fig. 2, a broken section taken on line 2 in Fig. l; Fig. 3, an enlarged perspective view of a finished crust; Fig. 4c, an enlarged broken perspective view of a tapering mandrel for holding the tins during the operation of winding the dough thereon, and Fig.

` 5 an enlarged broken perspective view of ejector mechanism.

A is a standard formed at one side with a stub-shaft a. At the top of the standard is a vertical sleeve portion b, adapted to receive and hold a vertical arm B, provided in its upper end with a horizontally-disposed bearingsleeve c. The arm B has a reduced downward-extending part d, fitting an opening through the sleeve I; and removably fastened in place by means of a set-screw e. Y

C is a mandrel having a hollow tapering head portion f and shank or shaft portion g. In the head portion f are longitudinal-extending slots L, disposed as 'indicated in Fig. 4. -The shaft portion g of the mandrel is journaled in a bearing c and beyond said bearing carries a pulley i. Extending through a central opening in the shaft g is a plungerrod lo, provided at its outer end with a knob or handle Z and at its inner end with radiallyextending pins or lingers m, passing through the slots t and projecting slightly beyond the surface of the mandrel.

J ournaled upon the shaft c, directly beneath the pulley z', is a pulley a, belted to the pulley fl. On vthe hub portion of the lpulley n is a ratchet-wheel p. Fulcrumed upon the shaft cv is a lever q, carrying spring-pawls r r, engaging the ratchet p. A spring s, connected at its upper end with the sleeve portion of the standard A and at its lower end with the free end portion of the lever, tends normally to hold the latter in the raised position. (Shown in Fig. 2.) D is a treadle connected by the rod or link-t with the outer end of the lever q.

An operator stands at the side of the machine, to the right in Fig. 1, with his foot upon the treadle D and his chest at or adjacentto the knob Z. As many tinsE of frustoconical shape are provided as may be required for the number of cream-rolls that are to be made. These tins are all of a size and adapt-- ed to beslipped upon the mandrel C, as indicated. The operator places a tin E upon the mandrel and operates the treadle D, which through the lever q and pawl-and-ratchet mechanism described rotates the pulley n and through the latter the pulley il, mandrel C, and tin upon the mandrel. While the tin is rotating the operator presses one end of a narrow strip of dough upon one end thereof and guides it, whereby it is wound spirally upon the tin to the opposite end of the latter, where it' is broken oiI. The operator then presses the knob Z with his chest, causing the than several could by the old method in the same time.

The machine is of simple and inexpensive construction, and whileI prefer to provide it throughout as shown and described it may be variously modified in the matter of details of construction without departing from the spirit of my invention as defined by theclaims.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a machine for forming crusts, of the character described,a support,a mandrel journaled in the support, and adapted to receive and hold the hollow baking-form, and means for rotating the mandrel, substantially as described and for the purpose set forth.

2. In a machine for forming crusts, of the character described, a support, a mandreljournaled in the support, and adapted to receive and hold the hollow7 baking-forms, means for rotating the mandrel, and a form engaging ejector movable along the mandrel, substantially as and for the purpose set forth.

3. In a machine for forming crusts, of the character described, the combination of a support, a hollow tapering mandrel, journaled in the support, provided with an elongated slot and adapted to receive and frictionally hold the hollow tapering baking-forms, means for rotating the mandrel, a plunger movable within and extending beyond one end of the mandrel and a form-ejector pin on the plunger eX- tending through said slot, substantially as and for the purpose set forth.

4. In a machine for forming crusts, of the character described, a support, amandrel journaled in the support and adapted to receive and hold the hollow baking-forms, a pulley upon the mandrel, adriving-pulley, journaled on the support, and belted to the pulley on the mandrel, a ratchet-wheel on the driving-pulley, a treadle, and pawl-and-ratchet-actuating means between said treadle and drivingpulley, substantially as and for the purpose set forth.

5. In a machine for forming crusts, of the character described, a support, a hollow tapering mandrel journaled in the support and adapted along its forward end portion to receive and hold the hollow tapering bakingforms, and provided with alongitudinally-ex tending slot, a spring returned .plunger extending into the mandrel, from the rear end thereof, having a form-ejector pin extending through said slot at one end and in position, at its opposite end, to be pressed by the chest of the operator, and means for rotating the mandrel, substantially as and for the purpose set forth.
